PostQueen runs an MCP server at api.postqueen.ai. MCP, the Model Context Protocol, is how AI agents use outside tools. Give your agent one address and it can list your channels, schedule posts, add media and read how your posts did. There is nothing to install or run on your side.

​
Pick an address

Clients that still use the older SSE transport can connect to https://api.postqueen.ai/sse/YOUR_API_KEY.
docs.postqueen.ai/mcp is a different server: it searches these docs and cannot post. Use an address from the table above.
The API key is part of the address, so there is nothing else to fill in. Most agents take this one.
Each agent’s guide says which address to use and where it goes. The list is on AI agents.

​
Where the key is

Where the API key is: in the app, open Connections > API Keys. Only a workspace Admin or Super Admin can reveal or rotate it; other members see it masked. A workspace has one key, and each agent card on Connections shows your MCP address with the key already filled in.
Anyone with the key can post to every channel in the workspace, so treat it like a password. If it leaks, an admin chooses Rotate key under Connections > API Keys. The old key stops working at once, in every agent that used it, so update each one with the new key.

​
Sign in instead of a key

1

Add the sign-in address

Paste https://api.postqueen.ai/mcp-oauth-dynamic into the agent, with no slash at the end. Leave any client ID and secret fields empty: the agent registers itself with PostQueen.
2

Sign in and approve

The agent opens PostQueen in your browser. Sign in and approve the access. Only a workspace Admin or Super Admin can approve it.
3

Use it

The access does not expire on its own. To end it, open Connections > Approved Apps in PostQueen and revoke it.
Grok Bot, Grok, Gemini CLI, Perplexity Computer and NanoClaw cannot sign in. Give them the API key, in the key address or the Bearer header.

​
What the agent can do

The tools come in seven groups. The agent picks the ones it needs from what you ask. Every tool, with what it takes and what it returns: MCP tools.

​
What it cannot do yet

  • Delete a post.
  • Change a post’s text or time, or move a draft to scheduled. It can change a post’s settings.
  • Read channel numbers such as follower counts.
Do those in the app, or with the CLI or the API.

​
Check that it works

Ask your agent:
It calls integrationList and answers with the channels you connected. Channels that are turned off or need to be reconnected are left out. If the agent shows no PostQueen tools, or the connection fails, see troubleshooting agents.
